WATER-CLOSET GAGE.

Specification of Letters Patent.

Patented (lot. 19, 1915.

Application filed April 24, 1915. Serial No. 23,726.

To all "whom it may concern:

Be it known that I, GEORGE MroDLEToN, a citizen of the United States, residing at Providence, in the county .of Providence and State of Rhode Island, have invented certain new and useful Improvements in lVater- Closet Gages; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

This invention relates to new and useful improvements in automatically operating water closets and comprises a simple and eificient apparatus of this nature having various details of construction, combinations and arrangements of parts which will be hereinafter fully described, shown in the accompanying drawings and then specifically defined in the appended claims.

My invention is illustrated in the accompanying drawings, in which:

Figure 1 is a vertical central sectional view through the same with one valve open and the other closed. Fig. 2 is a similar sectional view with he valves reversed, one open and the other closed. Fig. 3 is a top plan view, partially in section. Fig. 4 is a sectional view on line H of Fig. 1.

Reference now being had to the details of the drawings by numerals, 1 designates a bowl and 2 a seat hinged at 3 thereon. A projection 4 upon said seat is provided with a knob 5 which is apertured for the reception of the valve stem 6, which latter has a valve 7 at its lower end adapted to engage the seat8 at the upper end of the water inlet pipe 9 from which a branching pipe 10 leads into the chamber 11. A spring 12 bears between the valve 7 and the upper end of the shell in which the stem is mounted and serves to normally hold the valve seated.

The knob 13 at the upper end of the rod is adapted to be engaged by the projection 4 when the seat is in "to position shown in Fig. 1 and serves to hold the valve 7 away from its seat to allow water to freely pass into the chamber 11.

Upon reference to the drawings, it will be noted that the chamber 11 extends about the upper portion of the bowl and is provided with a series of downwardly extending ribs 14:, forming compartmentsin which air is trapped and which is compressed by the ber 14.

The operation of my invention will be readily understood and is as follows :WVhen the seat is pushed down to the position shown in Fig. 1, water will pass through the,

pipe 9 and into the compartment 11, the water entering the compartments intermediate the ribs 14:, compressing the air which is trapped therein. hen the seat is down, the valve 16 will close the exit opening 15 and, when pressure is relieved from the seat, it will be eturned to its upright position throng the medium of the spring 12 which will close the valve 7 and allow the valve 16 to unseat which will permit the water within the compartment 14 to be forced out through the exit opening 15, thus permitting the bowl to flush and siphon, the water also passing through the apertures 20 formed in the compartment 21.

\Vhat 1 claim to be new'is 1. An automatic flushing apparatus for water closets comprising a bowl having an annular chamber therein with depending ribs forming compartments in which air is trapped as the water is introduced into the chamber, an inlet pipe leading to said chamber. said chamber having an exit opening leading into the bowl, spring-pressed valves controlling the inlet pipe and exit opening,

a seat having a projection adapted to close one valve and allow the other to open as the seat is raised from the bowl.

2. An automatic flushing apparatus for water closets comprising a bowl having an annular chamber therein with depending ribs forming compartments in which air is trapped as the water is introduced into the chamber. an inlet pipe leading to said chamber. said chamber having an exit opening leading into the bowl, spring-pressed valves, one for regulating the pipe through which Water is introduced into the chamber and the other for regulating the exit opening from the latter, a seat pivoted upon the bowl and having a projection adapted to close one valve as the other opens and allow the other to open and vice versa.

3. An automatic flushing apparatus for water closets comprising a bowl having an annular chamber therein with depending ribs forming compartments in which air is trapped as the water is introduced into the chamber, an inlet pipe leading to said chamber, said chamber having an exit opening leading into the bowl, a seat pivoted upon the bowl and having a projection with a head thereon, a spring-pressed valve adapted to regulate the inflow of water through the pipe, a stem connected with said valve extending through an aperture in said projection and head, and a spring-pressed valve adapted to close the exit opening when the seat is down.

In testimony whereof I hereunto ailix my signature in presence of two witnesses.
